    Show You Just How to Boost The Securing Performance of SKF Bear
    SKF birthing seals To keep appropriate lubrication problems and healthy working environment of the bearing, give full play to the working efficiency of the bearing as well as prolong life, the rolling bearing has to have an ideal seal to avoid lubricant leakage as well as dust, water vapor or other dust Invasion of points.

    SKF bearing seals can be split into two kinds: self-supporting seal and outside seal. The supposed bearing seal is manufactured to have a sealing efficiency device. Such as bearings with dirt caps, seals, and so on.

    The Basic Elements Of Purchasing INA Bearings

    When designing a new spindle, before selecting an INA bearing, first consider the spindle performance parameters, roughly determine the most critical performance, and then enter further exploration. (Including: spindle speed, spindle accuracy, spindle rigidity, spindle life, spindle heat, spindle reliability) After the spindle parameters are determined, the actual dimensions of the spindle (shaft diameter, length, bearing span) are determined. 

    According to the bearing type (ball or cylindrical roller bearing), arrangement (column number), drive mode (transmission belt, gear, motor, built-in motor), lubrication (grease, oil and gas, oil mist, spray) and other spindle parameter settings Its structure.

    Bearing radial load

    The INA bearings that mainly bear radial loads are radial bearings. The nominal contact angle of this type of bearing a0 <= 450. Roller bearings with the same ruler can bear larger radial loads than ball bearings.

    N-type and NU-type cylindrical roller bearings can only bear radial loads, and other types of radial bearings can bear both radial loads and axial loads.

    Bearing axial load

    The bearings that mainly bear axial loads are generally thrust bearings, whose nominal contact angle a0> 450. Thrust bearings and thrust angular contact ball bearings can withstand axial forces in one or two directions at the same time, depending on the structure. When the bearing force is particularly high, thrust cylindrical roller bearings and thrust spherical roller bearings are preferred.Thrust spherical roller bearings and one-way thrust angular contact ball bearings can withstand both axial and radial loads, and other thrust bearings can only withstand axial loads.

    Bearing length compensation

    Supporting a shaft and a bearing usually adopts a structure in which a fixed bearing and a floating bearing are combined. Traveling INA bearings compensate for shaft length errors and thermal expansion.NU type and N type cylindrical roller bearings are ideal free bearings. These bearings can compensate for their own length. The inner and outer rings of the bearing can be tightly fitted.

    Length compensation for sliding fit

    Non-separable bearings can also be used as swimming bearings. One of the two rings of this type of bearing adopts a fit, and there is no axial fixed surface. Therefore, a ring of the bearing can move on its bearing surface.After determining the size and type of precision bearings, consider the specific design of the bearings.

    Fully consider the bearing fatigue life, rigidity, heat and other factors, select the most appropriate bearing clearance (preload).After determining the design of the main shaft structure, the necessary conditions for actual installation should be considered.

    High-precision bearing installation shaft and bearing seat accuracy, tolerance fit, tightening force of set nut required for installation and fixing, INA bearing preload after actual installation and confirmation of internal clearance.INA bearings are precision fittings, and need to be handled according to the correct method during installation and use in order to extend the service life of INA bearings. ERIC BEARING LTD have rich stock for INA NUTR50-A,  pls click here : 


    The surface of the INA bearing is coated with anti-rust oil. You must carefully clean it with clean gasoline or kerosene, and then apply clean high-quality or high-speed high-temperature lubricating grease before installation and use. The effect of cleanliness on the life of miniature bearings and vibration noise is very large. But we have to remind you in particular that the fully enclosed bearings do not need to be cleaned and refueled.

    When lubricating INA bearings, the more grease is applied, the better. This is a common misconception. 

    The correct installation of INA bearings also affects the accuracy, life, and performance of the bearings. Therefore, the design and assembly department should fully study the installation of INA bearings. Hope to install according to the operation standard. The work standard items are usually as follows:

    (1) Cleaning bearings and bearing related parts

    (2) Check the dimensions and finishing of related parts

    (3) Installation

    (4) Inspection after installing the bearing

    (5) Supply lubricant
